Dear Group,

With Cygnus slowly getting into good position for imaging, there is a
wide variety of goodies it provides for the interested observer and imager.

Given the plethora of Barnard dark nebulae it offers, I thought I would
try my hand with one of the largest such objects just north of the
bright star Sadr.

More specifically, I pursued B343 which lies within a couple of degrees
just north of Sadr. For an image based on four hours total exposure, I
kindly direct you tohttp://www.perseus.gr/Astro-DSO-Nebulae-Dark-B343.htm. This is my first
attempt at a dark nebula and I would welcome all feedback. I have
checked around and cannot find any reference images for comparison B343
... if someone has pursued this particular object, I would love to see
your results.

Clear skies!

Anthony.

Great looking image and those dark nebula take plenty of exposure time
too. The web address I provide here is of the Ha region with Sadr in
the lower right hand corner. This was a total of 90 minutes in Ha and
45 minutes total in RGB with a FSQ106n and ST-2000 camera at Palomar
Mountain last year. I plan to return this year with a ST10XME and re-
shot that area for more detail and a little large field of view.

Thanks John. Great image.
